ELECTRIC-LIGHTNG FIXTURE.

Electric-Lighting Fixtures, of which the following is a speciiication.

Our invention relates to electric, lighting fixtures, and especially to fixtures which are designed for use outdoors, such as for street lighting.

An object of our invention is to provide a device of this kind in which the globe or shade surrounding the light'source will be securely supported and atthe same time the supporting structure be so constructed and so arranged with respect' to the .globe or shade that it will offer a minimum obstruction to the passage of the light rays. A furlther object of our invention is to provide a structure of the aforesaid character'in which the supporting members willbe effectually protected from the action of the weather. In order that our invention may be used in connection with lighting units evolving considerable heat, an object vwhich we seek to obtain is the provision of proper ventilation without substantially detracting from weather protection. Still another object of our invention is to provide a supporting means which will allow the ready removal 'of the part of the globe supported by it for the purpose of cleaning. We seek also by our invention to attain the vaforesaid objects by means of a simple and economical structure which may be conveniently attached or detached. l

1n carrying out our invention, we provide a two part inclosure or globe. The lower -part or base is adapted to rest upon a support such as a post or other suitable means. The top part or cover, which is preferably of such construction and material that it will act as.

a reflector, is supported by the lower part and is detachably held thereto by means of a novel clamping means which is located substantially entirely within the globe. Prefer. ably the said clamping means is an integral member and carries adjustable means for engaging `the lower part of the globe and also the cover to hold the latter firmly in place or to allow its ready removal.

ably, also, the clamping means carries means y whereby the cover is spaced somewhat from the lower part so as to provide suitable vene tilat-ion, the parts of the globe being so shaped that.` lthe space therebetween is eectively protected from the weather.

Our invention will be more clearly understood by referring to the drawing, in which Figure 1 is an elevation, partially in section, of a 4finiture embodying our invention, and Fig. 2 is ber forming part thereof.

In Fig. 1 of the drawing is shown a globe consisting of a lower part or base 10 and an upper part or cover 1`1; Both of these parts may be of transparent or frosted glass, but it is preferred to have the base of frosted glass and the cover of white opalescent glass so thatl the former will be mainly diffusing in function, while thc latter will be mainly reflecting. The base 10 is adapted to rest upon a post or to be otherwise supported by means not shown. i I,

The cover is clamped to the base by means of the clamping member shown separately in Fig. 2. The said member is preferably of metal and composes a lower ring 12. EX- tending from downwardly projecting lugs 13` secured to said ring upwardly to a centrally disposed support on spider 14 in which they are firmly held, are a plurality of wires or rods y15. These rods should be as few in number and as'sm `ll in section as is consistent with strength and wear so that they will obstruct as little light as possible. The ring 12 carries means which` as shown, are partially identical with the lugs 13 for engaging the baselO, This means, in addition to said lugs, comprises the adjusting screws 16 engaging with threaded apertures? in said lugs. The ring12 is also provided with the upwardly projecting spacing lugs 17. A pin 1S threaded at its upper end projects from the support or spider 14.

The cover 11 preferably so shaped as to Shed water and' is of such width as to extend somewhat beyond the sides of the base 10. The bottom thereof is preferably rentrant as shown at 19. The said cover rests upon the lugs 17 which in turn rest upon theltop edge of the base 10. A Ventilating space 20 is thereby provided between the cover and base. The threaded end of pin 18 extends through a cap 2Q resting on the said cover. A nut 23 which with the cap 22 may be ornaa perspective` of a clamping memto held ehe eovei l fest to the sai base. n
